JOHN KIE'WICZ, Olli' HYDE PARK, MALB'SACHUSETTS, ASSIGNOR T0 THE REECE BUTTON y HOLE MACHINE COMPANY, .-QF .IBOSTON, =MASSACHUSETTS, A CORPORATION OF theimprovenient thereof is adapted to' various classesand'descriptions of, sewing machines. I

The principal' object hereofis to provide for the ready setting of the needle in proper relative position by -a needle setting means' originally adjusted or standardized, so that in subsequent-,insertion of 'new needles by 4operators the same will invariably b e brought to the proper predetermined posl- OII. i' i `Another yobject hereofis to adapt such a {needle-setting means or device to that type of sewing machine wherein an oscillating needlebar carries an oiiset needle, or in which tle needle bar has an offset or enlarged head orhend uponl which the needle is secured or clamped with its butt end' pro-` jecting rearward therefrom.. Sometimes in a sewing machine of this type the enlarged or offset head of the needle bar is so shaped as to adapt it to overhang the bearing in which the n the presence of the bearing in this location wou d stand in the way of any-heretofore f known needle setting or stopping device.

It is an object khereof to provide a .needle `setting or stopping device which is capableA of being employed in the types of sewing machine referred to, illustrations of.

which are seen, for example, in. prior patents of Reece N o. 404,863, patented June 11, 1889, andDahl & Hagelstein No. 987,966, patented March 28, 1911.v

In the accompanying drawings forming a part hereof, Fi ure 1 1s a left side elevation of' one form o embodiment of the present invention in which for convenience the same is applied to the type of machine having a horlzontal needle bar and needle, such as is referred to in the rior' patents above iind stitching or for tinishing button-holes. Fig. 2 is a right side elevation of the forward end of the needle bar and the needle carrying device thereon.

-Fig. 3 is a top view of the parts shown in Fig. 2. Fig. 4 in perspective shows all of the needle securing and setting parts detached from each other, but in substantially their` proper relative position for assembling.= Fig. 4a shows a detailed end view of the needle stop.

Similar numerals or letters of reference designate corresponding parts in the several figures of the drawings.

A needle bar or carrier 5 is shown, this being of the type having an offset needle or` having an offset or enlarged forward end or head, 6, to which the oiiset needle 7 is secured by the needle clamp piece 8, or other convenient securing device. As will be seen herein and insaid prior patents, the needle is held in the securing device 8, so that the needlesbutt will project rearward of the offset. needle bar head. Such .an arrangement of needle bar and needle may be employed inl combination with a horizontal work support 9, which has a recess for the depression of the work therein, andwhich also has a needle passage as in said prior patents, a presser-foot 10, and a bender 11 for bending the work into the recess for the purposes of blind stitching or button-hole iinishing. A needle bar of this type should be irmlymounted, and the same is shown as having a rear bearing 12 and a front bearing .13, these being in the form of upright standards from the frame ofA the machine,` as in said prior patents. Any suit-l able connection, suchas. link 14, may be temployed oroscillating the needle bar.

will'bejseen that the enlarged head of the needle harris-not only offset, but is' so shapedas to overhang-.the .forward bearingy 13 `to a slight extent,'and` the specific form of needle "fdeviceherein isalso preferably ar:

range tofoverhang the bearing.

needle in placeA is through the clamp piece 8 already referred to, which may be arranged to press directly against the .needle while the latter lies in an open groove, seen more particularly at in Fig. 4, formed in the head 6. -Below the groove 15 is' seen a bearing ledge 16, the purpose of this being that the clamp. piece 8 of symmetrical.

Y form may bear with even. pressure atp-both its upperand lower. sides, namely,l 'against the needle and against the ledge 16. The

clamp piece has a screw shank 17, lprojecqt- 'ing through the head 6, and it is tightened..

in place by a clamp nut 18, beneath which may be placed a washer 19. On 'locating the needle in the lopen groove 15 and tightening the nut 18, the clamp piece' willf'firmly bear'on' the needle v'and hold it, at the sam'e, time permitting the quick detachment of- '-Somejpart of this needle stop 20 is arranged to 'project laterally' :with-respect to the needle, so as to be contacted by the needles buttfor determining the needles position.

Preferably this is accomplished by arranging the body of the needle stop in a longitudinal direction andl providing a laterally projecting lange 21 at the rear end, shown for convenience as of triangular shape.-

The needle stop 2O is to be secured to the head 6 so as to projectrearwardly therefrom, and as a matter of great convenience and simplification I have provided the stop 2O with an elongated slot 22, capable of engaging about the screw shank 17 of clamp piece 8, so as to be secured therewith when the clamp nut 1 8 is tightened. The'outer or rearward end of the needle stop 20\is also properly held or positioned, this being accomplished herein by means of-a screw 23, 'adapted to engage in a threaded :longitudinal hole 24 in the head 6. The clamp piece 8, and the screw 23 coperate to hold' the needle stop in a definite position. At the same time the position of the needle stop is adjustable by the adjustment of the screw 23 inward and outward. The screw 23 and the stop 20 are shown connected to each other by a mutually engaging slot 25 in the triangular flange 21 of the needle stop and.

the annular groove 26 near the head of the screw 23. By this arrangement, upon loosening the clamp nut 18 the screw 23 may be turned for adjusting the position of the needle stop flange 21. When the parts are properly'adjusted and the needle is secured in place, the clamp nut 18 holds the parts against accidental dig gcement. At the same time, the needlcsfeasily detachable and replaceable bylooscning the 'clamp nut, andl as explained, the needlestop is origimanner to such 'position that each needle upon insertion will bear its proper and accurate relation to the other parts of the machine. When the screw 23 has once been engaged in the recess 25 of the flange 21, said flange may be slightly distorted so as to somewhat close the recess about the screw, thereby rendering permanent the connection between the two and preventing accidental displacement, in a manner, for example, as indicated in Fig.` 4a.

It is obvious 'that many matters of arrangementdcombination and mere detail may be indefinitely varied and it is therefore des'irednot to'restrict the present application pended claims.-

By the above-described devices, combinations and arrangement, it will be seen that the objectsand advantages before recited are attained, and other advantages will be perceived by those acquainted with the art to which the invention relates.
